"Indeed Allah, Most High said: 'O son of Adam! Devote yourself to My worship, I will fill your chest with riches and alleviate your poverty. And if you do not do so, then I will fill your hands with problems and not alleviate your poverty.'" (Using translation from Tirmidhī 2466)
"إِن الله يَقُولُ: يَا ابْنَ آدَمَ تَفَرَّغ لِعِبَادَتى أمْلأ صَدْرَكَ غِنى، وأسُدُّ فَقْرَكَ، وإلا تَفْعَلْ مَلأتُ يَدَيكَ شُغْلًا، وَلَمْ أَسُد فَقرَكَ".
